PREPARE to enter the "Danger Zone" with scantily-clad Old Spice star Terry Crews, who stars in a stimulating new commercial that sees him wired up to a music making machine.

The world's first muscle-powered television advertisement sees Expandables star Terry Crews wired up to a series of makeshift musical instruments.

Each time the actor and former NFL football player flexes his (highly impressive) muscles he makes a sound.

Once the advert has finished playing, viewers are invited to create and record their own version using their keyboard: a list of keyboard shortcuts is here.

Dubbed a “first-of-its-kind embeddable interactive experience,” Old Spice Muscle Music allows anyone to record their own percussion-laden jam session after streaming the former NFL athlete's impressive demo.

As much an advert for the technological prowess and innovation of advertising agency W+K, production company MJZ and VFX company The Mill, the interactive commercial is an exciting new development in web advertising.

The commercial echoes Google's recent playable Moog synthesizer, which invited searchers to compose mini masterpieces on the Google homepage, on an interactive, playable logo inspired by the instruments with which Dr Robert Moog brought musical performance into the electronic age back in the 1960s.

Crews replaces previous Old Spice Guy Isaiah Mustafa, another former American Footballer who shot to fame in a viral web phenomenon as "the man you could smell like."

The promotion took on a life of its own with numerous parodies and Mustafa posting YouTube responses to questions from Ellen Degeneres, Alyssa Milano, and anonymous tweeters on the web in real time.

Mustafa has since scored a Hollywood movie role alongside Jennifer Aniston in the film Horrible Bosses.
